CALIFORNIA CONCRETE-FORM-BINDING TOOL Application led December 9, 1927.Serial No. 238,985.

Our invention pertains to wire and strap iron snubbing brackets forbinding concrete structural forms inrigid position, and has for itsobjects, among others, to provide a tool which can be easily and quicklyplaced by one man; that does not mar the lumber; by which the bindingwire or strap may be tightened to any necessary degree and that may belocked in taut position instantly; that is simple in operation, durable,economical of employees time, and cheap to manufacture.

These objects we attain by the provision, formation and assemblage ofthe members and parts illustrated inthe accompanying drawings, in whichFigure l is a side elevation of the complete tool.

Figure 2 shows application of the tool in two positions on the form workof a concrete Y Y2c wall.

Figure 3 is a cross section of the operating bracket and lever handle inclosed position (A), and open position (B), and the gripping memberstherein.

Referring more particularly t0 the drawlngs: I

1 indicates the operating bracket of the tool, and 2 indicates acompanion bracket for the fixed end of the wire or strap.

3 indicates a hollow lever handle, pivoted within rearwardly projectingIianges of bracket 1, on pivot 5.

4 indicates al rectangular transverse block riveted to handle 3 toprovide an integral 35 part thereof.

6 indicates a rectangular transversely positioned block eccentricallyrevoluble on pivot 5 and adapted to co-act with block 4 in grippingaction.

7 indicates a wire or strap adapted to hold outside and inside wales ofa concrete form in rigid position toprevent spreading.

8 indicates transverse slots stamped in the rear face of bracket 2,adapted to allow a` metal strap to pass therethrough for snubbingpurposes, the metal between said slots being stamped to form a grooveexterior to Vthe body of the bracket adapted to receive wire 7therethrough for snubbing purposes.

s 9 indicates a resilient tongue formed crescentically to projectinwardly from the surface of any side face ofthe brackets, adapted tohold the bracket in position on the Wale while the other bracket andbinding wire or l tapeare being positioned.

4 and 6 (not shown) -to afford safer gripping y for wire, and to avoidshearing the same.

Y The brackets herein described are intended to be placed atintervals ofapproximately 24 inches on the horizontal wales, and to avoid sldepullor twisting effects thereby it is best to stagger them, i. e. thatthe bindingwire or strap be placed above and below the wale alternately.The position ofthe lever handle 1n closed position, up or down, is shownin Figure 2.

The procedure in proper use of this tool isto apply the binding wire orstrap (as the case maybe) and snub-one end in vbracket 2,

through groove or slots 8; place bracket 2 on a wale where tongue 9 willhold itin place while the other end of strap y"I is passedthrough theform to bracket 1 which has been positioned kon the corresponding wale.The loose end of strap 7 is passed between gripping members 4 and 6while lever 3 is in open position. K one hand on the exposed end ofstrap 7 lever handle 3 is moved from open to closed position, thismovement serving to automatically grip strap 7. As the movementprogresses the slack or strap 7 is taken up to.

a maximum of the diameter of the circle described by the contact pointsof members 4 and 6. y

Any degree of tension on the strap less than the maximum isreadily'controlled by the While traction is made by- Cil Seo

amount of hand traction when the movement of handle 3 is begun.

Reversal of the above outlined process will serve to release thetraction on strap 7 and the brackets may be removed, although it is moreexpeditious to cut the strap at convenient points and then clear thebrackets.

It will be apparent that various changes and modilications may beresorted to without departing from the spirit and scope of ourinvention, and we do not wish to limit ourselves to the-fexactdisclosures herein. p

Having thus disclosed our invention and its mode of operation, we claimas new and Vseek Letters VPatent Aof the United States upon: f Y
